I currently have an iPhone 4 (iOS 7) and I plan to upgrade to iPhone 6 (iOS 8), but I'm not sure how the backup and restore process will work. Normally I use iCloud for backups, so I'm thinking I'll try the following steps: 1. Backup my iPhone 4 (iOS 7) to iCloud. 2. Purchase new iPhone 6 (iOS 8) and restore from iCloud backup. However, I'm not sure if it is possible to restore an iOS 7 iCloud backup to an iOS 8 device. What's the best way to go about this? Thanks very much in advance to anybody who can answer this question for me. Cheers!
